Hadith 4:413

Narrated 'Imran bin Husain:

Some people of Bani Tamim came to the Prophet and he said (to them),
"O Bani Tamim! rejoice with glad tidings." They said, "You have given
us glad tidings, now give us something." On hearing that the color of
his face changed then the people of Yemen came to him and he said, "O
people of Yemen ! Accept the good tidings, as Bani Tamim has refused
them." The Yemenites said, "We accept them. Then the Prophet started
taking about the beginning of creation and about Allah's Throne. In
the mean time a man came saying, "O 'Imran! Your she-camel has run
away!'' (I got up and went away), but l wish I had not left that place
(for I missed what Allah's Apostle had said).
